Add a new port of crt-royale.fx (#3260)

- A new port of crt-royale. More faithful to original. It uses the same mask textures.
- The only thing not ported is the original geometry pass. It was replaced by geom curvature code.
- It's configured for 1080p displays. 4k displays need to adjust param mask_triad_size_desired from 3.0 to 4.0.

OBS: It's up to you decide if the two versions should be maintained.
